“…This is of fundamental importance when efficiently limiting metal mobility and bioavailability in ecosystems as well as obtaining gas and bio-oil byproducts with low or no presence of contaminating HMs. Moreover, metals containing biochar find valuable application in pollution-resolving issues such as dye removal or the elimination of organic contaminants from wastewater, through photocatalytic activity (Cd biochar) [80,81]. This is also the case for Mn-containing biochar, obtained from Phytolacca acinosa Roxb., and post-phytoremediation residues that have been utilized for the combined decontamination of Pb and tetracylin, as reported by Zhou et al [82].…”

Phytoremediation is an eco-friendly technology that utilizes plants and plant–microbe interactions to remove a wide spectrum of organic and inorganic pollutants from contaminated environments such as soils, waters and sediments. This low-impact, environmentally sustainable and cost-effective methodology represents a valuable alternative to expensive physical and chemical approaches, characterized by secondary pollution risks, and is gaining increasing attention from researchers and popular acceptance. In this review, the main mechanisms underlying the decontamination activity of plants have been clarified, highlighting the environmental remediation in fertility and soil health. Studies have illustrated the high potential of phytoremediation coupled with green and sustainable biocatalytic processes, which together represent a non-polluting alternative for the conversion of plant biomass into renewable resources. The convenience of this technology also lies in the valorization of the bio-wastes towards biofuels, energy purposes and value-added products, contributing to an effective and sustainable circular approach to phyto-management. The strategy proposed in this work allows, with the use of totally green technologies, the recovery and valorization of contaminated soil and, at the same time, the production of bioenergy with high efficiency, within the framework of international programs for the development of the circular economy and the reduction of greenhouse carbon emissions.

“…There is a multitude of plant species, as mentioned above, that may be utilized for synchronized phytoremediation as well as production of valuable phytoproducts such as aromatic oil, bioethanol, biodiesel, bioplastic, fiber, charcoal, wood, and alkaloids. (Khan et al, 2023). Phytoproducts, especially bioenergy is getting global consideration as a source of clean energy and additional income in the form of bioeconomy.…”

Land degradation and soil contamination have become global problem due to irresponsible anthropogenic activities and the overutilization of natural resources by humans. Land degradation and contamination due to toxic heavy metals have adversely impacted not only crop productivity but also the overall environmental health of our planet. Mitigation and management of polluted land are urgently required to achieve the goal of sustainable development because of the continuous human population explosion. In recent years, the biodiversity under phytoremediation is gaining scientists' attention for utilizing polluted lands and obtaining a bio‐based economy aimed at economically valuable and nonedible native plants. In the present review, we have focused on the biodiversity prospecting and phytoremediation potentials of economically important native plants, which may open up new horizons for sustainable development and redevelopment of polluted land sites.

“…However, the main considerations for its widespread use are associated with the imperative need to manage the biomass generated in this process. Strategies such as composting, leachate compaction, combustion, gasification, pyrolysis, torrefaction, and recovery of metals or other contaminants that do not reach complete degradation have been investigated in addition to the purposes previously mentioned (Khan et al 2023 ). It is crucial to gain more knowledge about how plants transform chemical components, the uptake routes, the mobility of contaminants, and their interactions in other tissues, how plants respond to this stress, and how they accumulate environmental chemical contaminants (Kurade et al 2021 ).…”

The 2030 Agenda, established in 2015, contains seventeen Sustainable Development Goals (SDGs) aimed at addressing global challenges. SDG-06, focused on clean water, drives the increase in basic sanitation coverage, the management of wastewater discharges, and water quality. Wastewater treatment could contribute to achieving 11 of the 17 SDGs. For this purpose, phytoremediation is a low-cost and adaptable alternative to the reduction and control of aquatic pollutants. The objective of this study is to highlight the role of macrophytes in the removal and degradation of these compounds, focusing on Eichhornia crassipes (Mart.) Solms, commonly known as water hyacinth. The reported values indicate that this plant has a removal capacity of over 70% for metals such as copper, aluminum, lead, mercury, cadmium, and metalloids such as arsenic. Additionally, it significantly improves water quality parameters such as turbidity, suspended solids, pH, dissolved oxygen, and color. It also reduces the presence of phosphates, and nitrogen compounds to values below 50%. It also plays a significant role in the removal of organic contaminants such as pesticides, pharmaceuticals, and dyes. This study describes several valuable by-products from the biomass of the water hyacinth, including animal and fish feed, energy generation (such as briquettes), ethanol, biogas, and composting. According to the analysis carried out, E. crassipes has a great capacity for phytoremediation, which makes it a viable solution for wastewater management, with great potential for water ecosystem restoration.
